Table 3 Households with larvae or pupae positive containers (Household index) and temephos presence in surveys in Managua control sites between 2005 and 2013

Survey date	Percentage of households with temephos observed in any container	Temephos observed in any container		Temephos not observed in any container		OR (95% CI)^a
Survey date		No. of inspected households	No. (%) with any positive containers	No. of inspected households	No. (%) with any positive containers	OR (95% CI)^a

Oct 2006	25.1	644	171 (27)	1992	430 (22)	1.18 (0.95–1.48)

Jan 2013	23.7	966	298 (31)	3108	599 (19)	1.82 (1.53–2.17)

OR of >1.0 indicates that households with temephos present were more likely to have a positive entomological indicator; italic font indicates the association was significant at the 5% level
